To eil whom it may concern.'

Be it known tl eti, JOHN lli-win BAKER, e citizen oi the United States, residing; et Lishon, in the county of Columbiana und State of Ohio, have invented n., 'new und `useful ldrietionearing ol'V which the following is e specification.

Th" invention relates to friction driving ineens for automobiles or selt- )ropelled hieles, but its use is not limited to this type oi` mechanism, inasmuch as it een be advantageously employed on nienv machines end mechanisms where change oi' speed or power is desirable.

The principal object of the present inven-V tion is to provide novel ineens of e very simple nature 'for etici-,ting the frictions-l engagement between thecoeeting friction members so es to secure e yielding contact, the 'force of which een be increased ns desired, und e further end importent object is to provide improvements in the dill'erent details of oonstruetion in order to secure e high degree of eilieiency in the mechanism e whole.

A further object is to provide in a strueture of this character, an adjustable driving disk which is carried by the engine or drivingl shaft, but which does .not require uny end wise movement of theI shuftovhen the disk adjusted..

The )referred einlmdiinent ol the invention is illustrated in the eeeoinpunyiiug drewings, wherein JDgS.

ln the embodiment illustrzitmll e suitable su porting ironie 7 is provided, which is pro-I vi(` ed with spared cross bers ln these cross hers und in the end ol' the 'l'ruine` is jouriuiled the usuul driving` or engine slnilt 9. Slidnbly ,mounted on the reur end of the sheit Q is e friction disk l() luiving' e, lint rear friction .ieee 1I. The disk l'eethered, es shown et l2 to seid shalt so that while .its sliding movement is not interfered with, 1t

, is held against rotation on the shaft, but is of course roteteble therewith.

A driven shaft 131s disposed across und contiguous to the friction tace 11 of the dlsk 1,0.` and is provided with fnsuitaible sprocket 6:3

,vhee-l 14 or other ineens .lor transmitting iower. On this shaft is loosely journnled e iriction wheel 15 that is in frietional engage nient with the face 11 of the ldisk l() on one side of the exis of rotation of said disk. Anl other friction wheel 16 is slidehle upon the shaft 1.3,end-is movable toward and from the wheel 15, being feathered on the shaft, as shown et 1-7. The friction Wheel 15 is norinnlly in Contact with the 'irictienface il of 70 the disk, and is movable from the periphery ol said disk l)est the center or exis of moveinent thereoi', This operetionis secured b ineens oi e controlling lever 1.8 having a lin' connection 19 with a bell crank lever 20. 75

The seid lever is provided with e yoke l that engages in e groove 22 iorined inthe hub ol the wheel' lo.. By swinging the lever, it `will he evidentv that the wheel een be inoved'lonafleverrB/l, fulerunied between its ends, as g5 shown at 25, has n. yoke 26 that engages the coller. This lever has a. link connection 27 et its outer end with an actuating lever 28. The coller, ns shown, is disposed on the opposite side of the cross bar S to the disk, and has gg n sleeve 29, which constitutes ny rear journal beni-ing lor the shaft, stud sleeve having its roer end slidablv mounted on the hub 30 of the shaft und hei/ing e flange o r shoulder 31 that abut-s against the. front face of the disk.

Draft pins, preferably in the forni of headed screws 31a are slidebly passed through the flange 31, and are engaged in the disk 10. It will thus be evident that the coller 23end sleeve are .movable with respect to the disk. A spring 32, housed within the sleeve, has its front end bearing against the rea-r end of the coller 23, while its rear end beers against the front end of the hub 30 of the disk.

Another spring 33 hears against the front los end ol the collar, 'and serves to equalize the pressure upon said Coller.

'The operation of the structure is as follows: li tl 1.o lever 28 is swung rearwardly, the 'sleeve 29 will be moved rearwardly upon the shaft 9, 11o

50 disengnge the disk ble into and out of coaction with the mem- 7. In mechanism, of the character set forth, the combination with a shaft, of a friction wheel slidably mounted on the shaft, means for sliding the friction wheel, another shaft disposed at substantially right angles to the first mentioned shaft, a friction disk slidably mounted on the last mentioned shaft and movable into and out of .frictional engagement with the wheel, a collar slidably mounted on the latter shaft, means for sliding the collar, a sleeve carried by the collar and having a slidable engagement with the disk, said sleeve and disk having shoulders arranged to abut, a spring located within the sleeve and interposed between the disk and ycollar, and another spring bearing against the opposite side of the collar to the first mentioned spring.

8. In meclianism of the character set forth, the combination with a shaft held against longitudinal movement, of a disk slidahle on one end of the shaft and having f an outer friction face, means for slidin the Ldisk longitudinally of and upon the siaft,

another shaft disposed across and adjacent to the friction face of the disk, a friction wheel slidable on said latter shaft, and means for sliding the wheel longitudinally of its shaft, l

9. In mechanism of the character described, the combination with angularly dis- 'osed driving and` driven shafts held against liongitudinal movement, of a friction disk longitudinall movable on one of the shafts and rotatab e therewith, a friction wheel longitudinally movable on the other shaft and rotatable therewith, said friction wheel cooperating with the disk, and means for moving the disk and wheel longitudinally of their respective shafts.

10. In mechanism of the character described, Vthe combination with angularly disposed shafts, each shaft having its axis of rotation intersecting the axis of rotation of the other shaft, of bearings for said shafts that hold them against lateral and longitudinal movement, a friction disk slidably mounted on one of the shafts, means for moving said disk on its shaft toward and from the other shaft, a friction wheel slida-bly mounted on said other shaft and coperatin with the disk, and means for moving t e friction v wheel on its shaft towards and from the axis of the disk.

i1, In mechanism of the character described, the combination with an engine shaft, held against longitudinal and lateral movements, of a friction disk slidabl mounted on said shaft and held against relative rotation with respect to the same, means for effecting the sliding movement of the disk, a driven shaft disposed transversely of the friction face of the disk and held against lateral movement, a wheel slidably mounted on the ldriven shaft and held against relativerotation with respect thereto, the periphery of said wheel coperating with the friction face of the disk, and means for effecting the sliding movement of said wheel.

12. In mechanism of the character set forth, the combination with a friction mem ber of a shaft, a second friction member mounted on the shaft and movable into and out of cooperation with the first-mentioned member, an operating device movable longitudinally of said shaft, a spring interposed between the operating device and. second friction member and bearing against one side of the former, and an equalizing spring bearing against the opposite side of the operating device.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
